Want to “hiss” about your recent experience at the airport or complain about your overcast vacation without losing followers? Look no further.

In response to a recent study that found being overly negative in your tweets as the second most harmful factor in growing an army of Twitter followers, Twitter has announced a new service for all of those not-so-happy tweets: HisSr.

Now if you’re in a particularly poor mood or you just HAVE to make your bad experience known, don’t throw a hissy fit, just use HisSr. All of the same rules apply: 140-characters, shortened links, etc.

Aside from the content of the tweets/his$es, one of the other main differences will be the standard colors of your profile (rather than the refreshing blue, His$r will be predominantly black). You’ll also be able to create a new alias, so that instead of “@Nancy,” you might name yourself “@Negative_Nancy.” Even cooler – get used to the “$” to group your dislikes instead of the traditional “#” hashtag.

But what are the implications of a service like this? Remember a little over a year ago when there was speculation about the addition of a “dislike” button on Facebook? Though it turned out to be just a scam, maybe we’ll see a “deFacebook” soon?

Personally, I try to be as positive as I can be on Twitter – it’s just more refreshing that way. There are definitely occasions when I really want to let a certain brand know just how much they’ve messed up. But, usually I keep my negative thoughts to myself, in favor of keeping my followers happy as well. I may or may not create a His$r account, but I’ll definitely check it out when it launches next week.

…April Fools!

Nope, Twitter won’t be introducing any “negative tweet only” service…at least not any time soon!
